I now have 12 of a brand called [Tenavolt], and generally like them….so far.

FYI, I did a quick write-up on these, in case anyone is interested:

TENAVOLTS AA Lithium 1.5V rechargeable cells

I picked these up on a whim, more out of curiosity than any particular need. This was a set of 4 cells and a charger, although I believe you can buy the cells separately as well. These are basically 13430 3.7V 750mAh Li-Ion cells with a buck regulator that maintains constant 1.5V output throughout the entire discharge cycle, wrapped in AA shell. Such output is good for applications that have trouble with 1.2V output from a typical NiMH cell, but it’s also bad because there is no way to tell how…
